GeForce GTX 1070 Ti vs Radeon RX 5500 XT

Intro

Compare all that to the Radeon RX 5500 XT, which features core speeds of 1717 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.

Radeon RX 5500 XT		130 Watts
GeForce GTX 1070 Ti		180 Watts
	Difference: 50 Watts (38%)

Memory Bandwidth

In theory, the GeForce GTX 1070 Ti will be 14% quicker than the Radeon RX 5500 XT overall, due to its higher bandwidth. (explain)

GeForce GTX 1070 Ti		262144 MB/sec
Radeon RX 5500 XT		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The GeForce GTX 1070 Ti should be quite a bit (more or less 62%) better at anisotropic filtering than the Radeon RX 5500 XT. (explain)

GeForce GTX 1070 Ti		244264 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 93168 (62%)

Pixel Rate

The GeForce GTX 1070 Ti will be quite a bit (about 87%) faster with regards to FSAA than the Radeon RX 5500 XT, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1070 Ti		102848 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 47904 (87%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
